A current controversy in memory research concerns whether recognition is supported by distinct processes of familiarity and recollection, or instead by a single process wherein familiarity and recollection reflect weak and strong memories, respectively. Recent studies using receiver operating characteristic (ROC) analyses in an animal model have shown that manipulations of the memory demands can eliminate the contribution of familiarity while sparing recollection. Here it is shown that a different manipulation, specifically the addition of a response deadline in recognition testing, results in the opposite performance pattern, eliminating the contribution of recollection while sparing that of familiarity. This dissociation, combined with the earlier findings, demonstrates that familiarity and recollection are differentially sensitive to specific memory demands, strongly supporting the dual process view.
当前记忆研究中的一个争议焦点是识别是否由熟悉度和回忆这两个不同的过程支持，还是由一个单一的过程支持，其中熟悉度和回忆分别反映了弱记忆和强记忆。最近在动物模型中使用接收者操作特征（ROC）分析的研究表明，对记忆需求的操作可以消除熟悉度的贡献，而保留回忆。这里显示，另一种操作，特别是在识别测试中添加响应截止时间，会导致相反的表现模式，消除回忆的贡献，而熟悉度的贡献则不受影响。这种分离，加上早期的发现，表明熟悉度和回忆对特定的记忆需求有不同的敏感性，强烈支持双过程观点。
